1. nPower Personal Energy Generator
Earth Day is April 22, so it’s a great time to take a step back and look at your personal energy consumption. Tech tools are often energy hogs, so we’ve compiled a list of the gadgets that do just the opposite.
Our first gadget is the nPower Personal Energy Generator (PEG), a $130 charger that uses body movement to charge devices. Place it upright in your bag, and go about your daily business. Later, plug in your smartphone or other electronic device and it will begin charging. It can also charge with a USB port. Once the internal battery is fully charged, it holds it for 100 days sitting still. If it is moving around, it can stay charged even longer. If your phone is dead, shaking the PEG for 10 minutes will generate enough energy to make a short call.
2 The Bedol water clock
The Bedol water clock has been around for a while, but the fact that it’s cheap and seemingly useful landed it on this list. The $20 “Squirt” clock converts water’s ions into clean energy power to keep the clock running. Fill the clock with water and it will last six months. It’s a simple alarm clock, with one control panel for one alarm.
3 Bicycle-powered charger
In July 2014, you can purchase this innovative gadget: a charger that gets juice from a bicycle. Siva Cycle, a company that makes modern accessories for cyclists, had a successful Kickstarter campaign last summer to raise money for their Siva Atom, which hooks onto the axle of a bike wheel and is powered through the spin of the wheel. The more you ride, the more energy you generate. It’s about the size of an iPhone and costs $100. The company is also targeting this charger to people in developing nations who ride bikes but have no way to power any of their electronics.

4 WeMo Insight Switch
The WeMo Insight Switch from Belkin allows users to control the energy usage of home electronics from anywhere using an iOS or Android device. This Wi-Fi enabled plug is an addition to the WeMo smart home platform, and plugs directly into an electrical outlet. Connect it to the home Wi-Fi system and download the app. Users can turn electronics on and off remotely, create notifications for device usage, and monitor specific appliances.
5 TED Energy Detective
The TED Energy Detective is designed to help lower energy bills. It works with a building’s existing electrical system to collect, store, and analyze data. Clamps on the breaker panels around the main wires monitor the data. The most basic system is designed for breaker systems less than 200 amps. An Energy Control Center, part of the kit, works with Footprints software, which connects to any computer, smartphone, or router. The average user saves 5 to 30% of their bill using TED, which can accurately project monthly bills using the energy usage data the user puts in. TED systems start at $200.
6 Solar laptop charger
The Voltaic solar laptop charger has the ability to power smartphones and laptops on the go. Using a 16 watt solar panel, it generates power in the sunlight and is waterproof and lightweight. One hour of direct sun will provide about 45 minutes of laptop charge. There is also an included laptop battery that can be charged via solar power or DC car or AC wall charger. It costs $399.

8 Cyber Rain XCI sprinkler system
Cyber Rain XCI is a smart sprinkler system that conserves water for landscaping projects. It waters them based on their needs rather than a timer. The kit includes a wireless access point, which connects to the internet to receive live weather information.

The system automatically decreases the watering schedule on cold or humid days, and increases on dry, hot days. It adjusts based on the slope of the land and monitors broken valves.
9 Wind-powered charger
